There are many servers on RHEL 5.2 using cPanel/WHM without issue, yet there are a small number that are. Our staff has looked into this issue earlier today and believe this issue may have been caused by some servers inadvertently downloading updates from a bad mirror.

In the meantime, anyone experiencing issues as a result of upgrading to RHEL 5.2 is welcome to submit a support ticket to us at: http://tickets.cpanel.net/submit
